' Specification of Letters Patent.

Fntented ami o, isle.

Serial No. 662,347.

To all whom it may concern:

lie it known that l. 'lYiniUs J. ST \Nl-HE- rice. citizen of the UnitedStates, residing at mago, in the county of Cool; and State of l inois,have invented certain new and t h ll 0. e ul Improvements ini'liuton'iatic Sprinkle S ansjot' which the following a specification.

This invention relates to certain iprovements in automaticsprinHer-systems and the particular improvements which constitute thesubject matter upon which I claim a patent. relate to the means fordischargting, the water'into a room where the system is installed and tothe operation of a, snitable alarm device connected with such dischargeand operated by the flow of water through the discharge device.

More specifically, in invent-ion relates to a discharge nozzle havingeittensiole or telescopic functions. the means for supp0rti'ng saidnozzle when in inoperative position, and 21V rotatable alarm operatingdevice tion.

Some of the objects attained by the said improi einents are certainty inthe operation of the sgrinlzler when the conditions which call for itsuse are pres nt; the concealing of the apparatus until it. is needed inoporation, and the thorough distribution of the system of w sterdischarged from the nozzle through a editable sprinkler head.

in the accompanying drawings. l have ntion of in}! inv tion andimprovements in the followin views:--

Figure 1 shows partly in .I'E l nozzle in oi ierative pos tion andl'filll'lun when erected in the ceiling of an o notion of t room; Fig. 2is a cross matic alarm operating device with its odjacent' pipe sectons; Fin. 3 a longitudinal section of a portion the t lcscoping; in nhers of the nozzle and Fig. is a perspe tive View of a cap or closurewhich serves to conceal the nozzle when not in use and which isautomation j opened w en water is flowing through the noznle Referringto the details of he drawin represents generally" a castnictal whichconnected. thereto and con1niuni-- eating therewith pipe extensions 5*,If", which are placed. respectively at' the upper lower OD1ODS of thecasing serve as conductors for *ater to and from the casing. This casingis supplied with a cover 5" on one side which is i'einovahly connectedthemwith by screws Arranged transverseh. "f the casing" having suitablehearings in the rear wall and cover thereof is a spindle 8 on whichis'rotatably mounted a wheel '9,

to the periphery of which are pivotaily mounted a series of curvedblades 9 the pivoted ends of which are formed with shoulders 9 whichlimit the outward movement the blades as clearly indicated in Fitz.

gainst the wheel in the opposite direction.

The spindle 8 projects tln'oughthc casingcover 5 and has mounted thereona curved oawl 1.0 which rotates with the spindle. At

one side of and near the lower portion'of 2. while permitting the bladesto fold a the casing is a stud screw 1 on which is pivotslly mounted .atwo-arm lever 11, one arm of which 11 in the path of rotation otthepawl. 10, and the other arm 11 of which is supplied witha hammer 11 atits extremity which is so placed asto be brought into intermittentcontact with a bell l2 se cm to a pipe Y which extends fromthe branch 5'of the casing The upper end of the pipe 7 is screwed "ring; and twistedblades 16, 7. so arranged to eliect the rotation of this member as thewater discharged through the coupling 1%: impinges thereon.

The device above described is preferably iii-ranged snd'suitablysupported between the joists Q3 and the ceiling and floor which form theusual construction in buildings oi the class to which my invention isapplicw lole.

A l and 25 representrespectively the lath and plaster attached to theioists 23 in the usual manner. "he lath and plaster have been cut away,in part to provide a suitable opening for an annular socket plate 18'which set into the opening and supported hv the lathe. tnz'ewith acollar 18 on. the upper face of This late has connected I which are aseries of beveled lugs 19 formed with the overhanging-flanges whichserve to engage the lower flan e of the socket plate 18 and thus removaby attach the col-v lar 19 to said plate. Connected with the collar 19,by a huge 20, is a cover 21 which is provided with a spring latch 22 soformed and arranged as to engage the collar 19 and holdthe cover inclosed osition until the latter is subjected to sufficient pressure fromabove to overcome the tension of said latch.-

From the construction above described,

assuming that the nozzle is housed between the joists 23 and above theceiling connected with said joists, water through the casing wi forcethe blades 9 outwardly and thereby rotate the spindle I 8 with its pawlwhichwill produce an intermittent movement in the leverll and a.

consequent pounding of the hammer 11 against the bell 12*. Pressure ofthe water flowing through the pipe connection 5 and impingin on theshoulders atthe upper ends-of t e pipes 13, 13*, and the members 16, 17,will cause said pipes to move downwardly their full limit, thusbringing'the' discharge end .of the nozzle to a pos tion Within the roomwhere the water will be distributed most efi'ectively by the rapidlyrotating members 16,17. The same water pressure, it will be understood,will be sufiicient to force the cover 21' to its open position as shown,thus permitting the extensionof the sprinkler head proper to its fulloperative position. In order to facilitate the free rotative movement ofthe collar 14 with its yoke 15, I provide ball bearings 26 arranged asshown in- Fig. 3.

i I have not shown nor describedany means for automatically permittingthe water to 1 flow through the nozzle described because same forms nopart of this invention, which 1.
